fix(review-blocks): restore legacy palette values and mark token-gaps

The components pointed at the nearest existing token when the legacy
value did not match. That traded visual fidelity for token coverage,
violating the brief's first rule. Each offender now carries the true
legacy value with a token-gap marker naming the real reason and
design-system-keeper as the owner.

138 gaps flagged for design-system-keeper. Gate green.
